I kind of did, I know they have a good amount of modules for wiki like style site and that you can integrate MediaWiki with Joomla. But, I will have to look into Joomla more to know for sure that I can get the features I want.
By the way did any of you seen a wiki like site that runs in Joomla, even if its the demo site?
I did find demo site for the Drupal, but this is as good as it gets: http://test.tschannen.net/ (admin disabled Edit function in this demo)
In the demo you can see, "Revision" - shows you history of edit, "Talk" - Discussion, and "View" - viewing the article. And the "Edit" button which you can't see because Admin disabled Edit feature for Guests.
And here is the modules that can be used to achieve wiki like function in Drupal: http://www.starbowconsulting.com/blog/tao/wikis-drupal-6-module-review
Here are the down sides, If you were to look into any Wikipedia article you would see numerous  links, each edit link edits specific section of that article, in Drupal you only get one edit button to edit the whole article. Can I get more than one [edit ] in the Drupal? Yes! But, with out giving up "Revision" function, because each  will be a different node, which means there will be separate revisions for each node. So, all the revisions will not be stored in one place. Of course, there are few other problems that I am facing that are mostly with coding, and that Drupal community not really eager to help me out with. (Mostly PHP coding)
Most of my time I spend learning how to create add form like the one in WikiHow site.
But, if I just can get to work Wikihow clone site, that would be awesome, but again I am getting bunch of PHP errors there, and I am not PHP friendly user. Unless jackass want to help out, since he already have WAMP installed on his computer.
